Best time to visit the Rocky Mountain States
The best time to visit the Rocky Mountain States depends on what you want to experience and which specific destinations you're interested in.
June and September are generally considered the best times to visit due to the cooler, clear days, and there being fewer visitors to the national parks.
In the height of summer, July and August, you can take advantage of the longer days and for certain national parks, such as Yellowstone, this is the best time to visit for wildlife viewing. However it is important to note that the parks are likely to be crowded, prices can be higher and there is the potential for extreme heat.
Winter is great for skiing or snow boarding but you only want to visit the parks if you're going on a winter guided tour of Yellowstone or Grand Teton National Parks. Generally speaking the season in the Rocky Mountain States is May to September.
